schemaform adding the user input to a schema array - angularjs

Question

Background
I am making a form using angular-schema-form
Setup
I am trying to make an array of items that a user can make using a form. So, the user can add as many items into the array as they want.
For now the items in the array contain a command type.
Command Type should be a dropdown containing SSH, REST, and whatever the user enters in as the personalized command type.
Code so far
SCHEMA
{
"type": "object",
"properties": {
"personalizedCommandType": {
"title": "Personalized Command Type",
"type": "string"
},
"commands": {
"type": "array",
"title": "Actions",
"items": {
"type": "object",
"properties": {
"commandType": {
"title": "Command Type",
"type": "string",
"enum": [
"REST",
"SSH"
]
}
}
}
}
}
}
FORM
[
{
"type": "help",
"helpvalue": "<h5>Command</h5>"
},
{
"key":"personalizedCommandType"
},
{
"title":"Command",
"key": "commands",
"items": [
"commands[].commandType"
]
}
]
One can test this code here: http://schemaform.io/examples/bootstrap-example.html . Just copy and paste in my code.
Question
As one can see, the code I have now has a field with Personalized Command Type and an array of dropdowns with the 2 options SSH and REST. But I want to drop to also contain the value of the Personalized Command Type once the user has entered it.
NOTE
copyValueTo does not seem to have the functionality that I want given that it can only change values in the model, but I want it to change the enum array in the schema.

Answer 1

Use the onChange option:
[
{
"type": "help",
"helpvalue": "<h5>Command</h5>"
},
{
"key":"personalizedCommandType"
onChange: "updateSchema(modelValue,form)"
},
{
"title":"Command",
"key": "commands",
"items": [
"commands[].commandType"
]
}
]
Update the Schema:
var defaultEnum = ["REST","SSH"];
$scope.updateSchema = function(modelValue,form) {
var currentEnum = $scope.schema.commands.items.properties.commandType.enum;
angular.copy(defaultEnum, currentEnum);
if (modelValue) {
currentEnum.push(modelValue);
};
$scope.$broadcast('schemaFormRedraw');
};
